java实现斗地主游戏

感想：

第一次写博客，感觉编辑器挺复杂厉害的，感觉自己的内容挺简单的。有什么问题请多多指教！

思路：

1、创建一个扑克牌的实体类Poker，设置了四个参数：花色、数字、牌值（判断大小）、是否地主牌，实现getset方法和构造方法；
2、创建一个玩家的实体类Player，设置了四个参数： 初始牌集合，排序后牌集合，牌值集合，是否地主，实现getset方法和构造方法；
3、洗牌：循环嵌套花色数组跟数字数组生成52个Poker，手动加入大小王Poker，放进map(int,Poker)里面，利用Collections.shuffle随机排序map的key，再根据key生成排序后的Poker集合
4、发牌：生成3个玩家对象，拿到洗牌后的集合，前51张牌为玩家牌，后3张为地主牌，在51张牌中随机一张为地主牌，遍历玩家牌分配个每一个Player，同时根据玩家牌的牌值生成集合grades存进Player对象中，将grades转为int数组并进行升序排序，根据grade取得新Poker集合分配给玩家。

Poker类：

package com.company;

public class Poker {
private String color;
private String number;
private int grade;
boolean isLandowners;

public boolean isLandowners() {
return isLandowners;
}

public void setLandowners(boolean landowners) {
isLandowners = landowners;
}

public int getGrade() {
return grade;
}

public void setGrade(int grade) {
this.grade = grade;
}

public String getColor() {
return color;
}

public void setColor(String color) {
this.color = color;
}

public String getNumber() {
return number;
}

public void setNumber(String number) {
this.number = number;
}

public Poker() {
}

public Poker(String color, String number ,int grade,boolean isLandowners) {
this.color = color;
this.number = number;
this.grade=grade;
this.isLandowners=isLandowners;
}

public String toString() {
return this.getColor()+this.getNumber();
}
}

Player类：

package com.company;

import java.util.ArrayList;
import java.util.LinkedList;

public class Player {
private ArrayList<Poker> pokers;
private boolean isLandower;
private ArrayList<Poker> newPokers;
private LinkedList<Integer> grades;

public LinkedList<Integer> getGrades() {
return grades;
}

public void setGrades(LinkedList<Integer> grades) {
this.grades = grades;
}

public ArrayList<Poker> getNewPokers() {
return newPokers;
}

public void setNewPokers(ArrayList<Poker> newPokers) {
this.newPokers = newPokers;
}

public boolean isLandower() {
return isLandower;
}

public void setLandower(boolean landower) {
isLandower = landower;
}

public Player() {
}

public ArrayList<Poker> getPokers() {
return pokers;
}

public void setPokers(ArrayList<Poker> pokers) {
this.pokers = pokers;
}
}

洗牌：

/*洗牌*/
public static LinkedList<Poker> getPokerList() {
LinkedList<Poker> pokers = new LinkedList<Poker>();
LinkedList<Poker> newPokers = new LinkedList<Poker>();
ArrayList<Integer> arrayList = new ArrayList<>();
int[] arr;

/*生成54张扑克牌（Poker对象）*/
/*用嵌套循环生成从方块3到黑桃2的Poker对象，放进Poker的LinkedList保证顺序*/
String[] colors = {"♦", "♣", "♥", "♠"};
String[] numbers = {"3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K", "A", "2"};
for (int i = 0; i < numbers.length; i++) {
for (int j = 0; j < colors.length; j++) {
Poker p = new Poker(colors[j], numbers[i], (4 * i) + j + 1, false);
pokers.add(p);
}
}
/*添加大小王*/
pokers.add(new Poker("black", "☆", 53, false));
pokers.add(new Poker("red", "☆", 54, false));

/*将生成的54张扑克牌从1到54放进map*/
for (int z = 1; z <= pokers.size(); z++) {
map.put(z, pokers.get(z - 1));
}
/*遍历Map,将每个Poker对应的key放进 ArrayList<Integer> arrayList */
Set<Map.Entry<Integer, Poker>> set = map.entrySet();
Iterator it = set.iterator();
while (it.hasNext()) {
Map.Entry<Integer, Poker> e = (Map.Entry<Integer, Poker>) it.next();
arrayList.add(e.getKey());
}
/*利用Collections.shuffle随机排序key*/
Collections.shuffle(arrayList);
/*将乱序后的key对于的Poker放进newPokers里面 */
for (Integer i : arrayList) {
newPokers.add(map.get(i));
}

return newPokers;
}

发牌：

/*发牌*/
/*根据玩家人数生成Player，默认num=3*/
private static void sentPoker(int num) {
/*获取洗牌后的LinkedList,保证顺序*/
LinkedList<Poker> Allpokers = getPokerList();
ArrayList<Poker> pokers = new ArrayList<>();
ArrayList<Poker> BottomPokers = new ArrayList<>();

/*生成玩家对象*/
for (int i = 0; i < num; i++) {
Player p = new Player();
players.add(p);
}
/*前50张牌为玩家牌，后三张为底牌*/
for (int p = 0; p < Allpokers.size(); p++) {
if (p <= 50) {
pokers.add(Allpokers.get(p));
} else {
BottomPokers.add(Allpokers.get(p));
}
}
/*玩家牌中随机一张为地主牌*/
Random rand = new Random();
int s = rand.nextInt(51);
pokers.get(s).setLandowners(true);
System.out.println("地主牌: " + pokers.get(s));

/*根据num生成Player对象*/
for (int j = 0; j < num; j++) {
/*玩家的牌值集合*/
LinkedList<Integer> grades = new LinkedList<>();
/*玩家的手牌集合*/
ArrayList<Poker> playerPokers = new ArrayList<Poker>();

/*根据玩家个数分配玩家牌*/
for (int z = j; z < pokers.size(); z = z + num) {
playerPokers.add(pokers.get(z));
grades.add(pokers.get(z).getGrade());
players.get(j).setPokers(playerPokers);
players.get(j).setGrades(grades);
}
/*根据玩家牌中的地主牌设置玩家是否地主*/
for (Poker p : players.get(j).getPokers()) {
if (p.isLandowners() == true) {
 players.get(j).setLandower(true);
}
}
/*根据玩家的牌值集合生成数组*/
Integer[] gs = new Integer[players.get(j).getGrades().size()];
grades.toArray(gs);
/*排序数组，由低到高*/
Arrays.sort(gs);

/*排序后的玩家牌*/
ArrayList<Poker> newPokers = new ArrayList<>();
for (int g = 0; g < gs.length; g++) {
Poker p = map.get(gs[g]);
newPokers.add(p);
}
players.get(j).setNewPokers(newPokers);
System.out.println("玩家" + (j + 1) + ": " + players.get(j).getNewPokers() + " 是否地主：" + players.get(j).isLandower());
}

System.out.print("底牌为： ");
for (Poker p : BottomPokers) {
System.out.print(p + " ");
}
}

效果如下：
